No accounts or non-public data are involved."}},{"@type":"Question","name":"How often is it updated?","acceptedAnswer":{"@type":"Answer","text":"Top-level categories update every 3 hours, mid-level categories daily and long-tail subcategories about every 3 days. Crawling runs around the clock, and the home page shows when the latest data landed; long-tail categories with high opportunity scores are refreshed more often."}},{"@type":"Question","name":"How is the decision card verdict decided?","acceptedAnswer":{"@type":"Answer","text":"By public rules: strong median daily sales, a low review barrier, many low-review books, recent breakouts and a moving list add points; few buyers, a high review barrier, very low print prices and a frozen list take points away. Strong sales behind a high review wall read Crowded; weak signals or a small sample read Watch."}},{"@type":"Question","name":"How is the opportunity score calculated?","acceptedAnswer":{"@type":"Answer","text":"Review barrier, share of low-review books, churn, share of books released in 90 days and price room are weighted into 0–100, then multiplied by a demand factor from the Top 100's median estimated daily sales. Low-demand categories are capped at 40, so a niche nobody competes in because nobody buys there never ranks first."}},{"@type":"Question","name":"Do sales estimates include Kindle Unlimited?","acceptedAnswer":{"@type":"Answer","text":"No. BSR-based estimates count purchases only, not KU page reads, so fiction categories heavy on KU earn more than shown. Use them to compare scale."}},{"@type":"Question","name":"Does browsing the site use up calls?","acceptedAnswer":{"@type":"Answer","text":"No. Browsing is free; only API, MCP and Chrome extension calls count, and quotas reset daily at 00:00 UTC."}}]}]}
